To all whom it may concern: Be itknown'that l. Joux \\'i|.i.i.\.u ('i'al im: a citizen of tlie United States. ri-idiug at .linneapolis. in 'the county of `Hennepin und State of .\linne. ta. have invented eerz tain new and useful mprovenients iii llail- Flushing Mechanism for lmzoniotives; and

l do hereby declare the following to be a4 eonaiats of the novel devices and combination of devices hereinafter described n iid' deliaed in the claims.

' 'lhe improved mechanism is particularly designed `for use in mnneetion with a feed water heater of a locomotive, and it will be so described, although the invention obvioualy hna'othcr applieatiom. said,- hoivever, that a ateaui heated feed water heater conatitutes an especially reliable and vet economical l-'ouree of water for my rail flushing mechanism. such water being formed by the condensation of the steam used in heating: the feed water.

thron 'illustrato the invention, up hed ln the accompanying drawings, which lto a motive like characters in icnte like -parta ont the several views.

Re errin to the drawings, Figure 1 is a view in side elevation, with aonie parta broken away and some parta shown in diagram' only, illuatratin plied to an ordinal' oconiotive; Fig. 2 is a fragmentary vertical section taken approximately on the line ai w o1 Fig. 1; `fie. l is a horizontal section taken `on the line nz' w of Fig. 2, sonic parts bein broken away; Fig. 4 is an enlnrfged vertice section taken on theline'asfm o Figr; and Fig. 5 is an enlarged' vertical section showing the automatic regulating-valve.

The other chamber 9 is connected to the boiler. In ome calca, it will be directly connected to the boiler, but for a special urpoae'prcaently to'ba noted. it is connected iy a pi 'aeket 1 that surround# the upper portion .of thel amoko box 0 and ia, of courae, acleared thereto and to the otack 7 by' pater,- tightfjointe.

A light roiled spriiagr Ill, which reacts againstI the stalling box :tit and against a collar 35, on.

the stein 32, normally holds the valve 51 in its open position, shown in Fig. 4. The extended end of the stem 32 is connected to the lower arm 32* of a tiuiall upright rock mounted in suitable bearings on the engine frameand end with an arni 32'ndapted to` be enga d h ,v the engine reversin ever 4. The re ation between the arm 3 and lever 4 is such that when the raid levers in its neutral i tion, as when the engine is standin sti l or when the said lever is forced foi-wart as when reipiired to cause the engine to travel forward, the spring 34 holds the valve B1 iii its open position: but when the said lever is moved rearward to cause the engine to back up it engages the arm 32 and through the connections just described moves the valve 31into a closed position, against the tension of said spring. This latter action', as ia evident e ores the drip pipe 27, so that the rails will not he washed and iliade slippery when the engine is backing up. The exhaust steam from the heating drum 8, which ia not condensed before reachta latter delivered into 't ieteiu er tank for the purpose of warming, to some extent, the vwater contained therein.

. inayhe'stated that the condensation of the .steam delivered into the heater will kee 'a considerable flow of water which hon l lll) d be except when the engine permitted to escape,

even though the valve 38 he is hackingr up,

clos-ed. 'l'hei-w poi-hi 3,8, however, are` of auch size that they will he constantly tlooded with water, so that the steam pressure will `be available to open the valve 3S.

In the steam `i 20, whieh'eoiinects the exhaust ports' o .t e cylinders to the steam chamber 11 of the heatin drum, is a' cheek valve 20* which permits tlw of steam in the direction stated but checks a back-flow and .thereby reventa condensed 'steam from flooding t e cylinder exhaust .isorts.

The automatic checkvalve .is set under light tension so that, while it willnormally close the exhaust from the heating drum steam chamber 11, it will, neverthe el?, be

t o exhaust steam exceeds a ce ain predetermined point. Obviously, the higher the pressure of the exhaust steam the ter the extent to which the valve B will opened. This va va prevents normally closed latin too res y escape oi the auat atsam and causes the same, even when under low pres-i sure, to completely ll the steam chamber 11, thereby very greatl increaaingtho efllciency rthermore, affording an automatic "ariable relief port to the exhaust nozzle of the locomotive.

`Ona ot' the water chambers 9 of tha heater is `shown as direetlg connected tothe boiler 1 at apoint'below t e water line thereof by a pi 44, provided with a noi-mall closed shown as provided with a blowout-pigl 4 6 ien a normally closed valve 47. it is esired to wash out the heater, two ed u und hot water from the bo' er wi then forced to-wit, through 'the duel 11, under high pressure.
